    transformer_requires_async(
        transformer: StreamTransformer,
    ) -> bool

    Parameters

    NameTypeDescription
    transformer*StreamTransformer

    The transformer to inspect.

    Return True if the transformer needs a running event loop.

    A transformer requires async if it explicitly opts in (requires_async = True) or overrides any of the async-lane methods (aprocess, afinalize, afail) without also declaring that it supports the sync lane.
